Submersible(drainage)

BUM


Application

  • Sewer relay
  • Drainage for agricultural colony
  • Relay tank to sewer main and sewage treatment facility

Feature

  • The ability to pass foreign objects is 100% of the bore size (it can discharge spherical solids with a diameter which equals to the bore size).
  • The closed-type, high-efficiency, non-clog impeller (patent pending) and our original casing structure provide high pumping performance with high efficiency.
  • Combination of a Pre-rotation tank and a pump with bell mouth allows suction up to low residual water level, while discharging suspended particles and suppressing scum and bad smell.
  • Control panel for manhole pumps and necessary parts are also available as special accessories.
